There are some differences in the details with Brother M, but the idea of "single chip structure" and "URPD gap" is the same. The higher the accumulation of Bitcoin's single price, the greater the market's demand for direction selection. In 2022, the highest single price seemed to exceed 1.2 million BTC, and currently the highest single price is 722000 BTC. Then there is the gap in URPD, which has never been left unfilled in history. It is a matter of time, and the gap in URPD is different from CME. CME can only be filled when the price reaches this point, while URPD has a new high again, and there is a probability of being filled after recalculating URPD. Last time when URPD broke through $120000, there were two gaps, namely $112000 and $114000. The latter has already been filled, while the former is still waiting.
